Permeability Test Method of Concrete Member under Uniaxial Tension Stress

Abstract:

Article Preview

Concrete member is usually stressed in structure. To test permeable behavior of concrete under load is significant in clarifying this characteristic. Currently, most of the methods measure the permeability of concrete specimen without stress. This paper describes a method that measures permeability of concrete subject to a uniaxial tension load. The main components of the test device include two parts. One is tension loading system, and the other is permeability system. The concrete member with 100×100×1000mm is designed to be the sample. A uniaxial tension load could be applied to the prism concrete specimen and the load was allowed to increase by steps until failure. Autoclam is adopted as permeability system. At each ground of the tension load the volumetric water flow through specimen is recorded with data acquisition automatically. The relationship between water permeability and increasing stress could be obtained with the suggested method.
